ALvAN is. BROWN, or BENTON nieren., MICHIGAN. l

\\\\ f .r/ ToaZZ whom t may concern Be it lmown that It ALVANv B. BROWN,a

citizen ofv the United States, residing at Benton Harbor, Michi an, haveinvented certain new and usef rImprovements vin Sprayers, off/which thefollowing is a specifi'cation.

This improvement relates to ,improvements in sprayers.

My f'mproved sprayer is .,fspecially de-k signed by me for use inspraying fruit trees and the like Where the spray is directed by theoperator on the ground or on -a Wagon or spraying machine. n

The main objects-of this inventionare to provide an improved sprayer" inwhich the character of the sprayer may be changed Yat will, which isvery effective and at the same time simple and economical in structure,durable in use and notl likely to Abecome clogged.

Further objects, and objects relating tov structural details willdelinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devicesand meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawing forming a part of thisspecification, in which:

Figure I is a detail side ,elevation of a structure embodying thefeatures of my invention. Fig. II is a detail longitudinal sectionthrough the sprayer head. Fig. III is a transverse section on a linecorrespond- .ing to line 3)-3v of'4 Fig. II. Fig. IV 'is a detailsection on a line corresponding to a line 4 4 of Fig. I. i In thedrawing similar refe'lencc characters refer to similar partsthroughoutvthe several views, and the sectional views are taken lookingin the direction of the little arrows atthe ends of the section lines.

.Referring to the drawingv the delivery pipe l is of suitable size andlength for the convenient .manipulation of the sprayer, itconstituting'a handle and being in'practice I.Visually about eight i'eetin lengthy and connecte'd tothe source of supply under' pres-v sure ortoa force pump by means cfa iiexi ble pipe tube 2.

with a-.valve 3 at.its lower end. The'sprayer head or body is elbowshaped so that V`its face or tip 5 is directed. laterally. The face ortip member 5 is provided. with a threaded flange 6 .threaded upon thebody.. The tip 5 `has a central delivery orifice 7. A disklike plate 8is arranged Within the body, it being supported by the lannular shoulder9.

The tipmember and plate are supported in a spaced relation by means of agasket 10 which 'not only spaces the members to provide the chamber `11,ybut also seals the joints. `'Ihe member 8 is provided 'with deliverypassages 12 disposed to deliver at 'an angle into the chamber 11, whichcauses tially at right angles withv a longitudinal y axis of the pipe l,,Which is threaded into the inner end of the nozzle head or body 4,

as shown in Fig. II. The lvalve stem -17 is arranged through theinnerend of the body 4 and provided'vvith a 'packing lgland 18. The valvestein 17 is in the form of a rod and is disposed parallel to the pipe 1.The valve stempasses through the' guide 19, which also serves as asupport for the valve return spring 20, lthe upper end of the spring"being, connected with the valve through the Washer 21 and Cotter pin22. The valve actuating lever 23 is pivotally mounted on the pipe l bymeans of the clip 241 and is ivotally connected with the valve stem bytlie pivot 25. When the valve 16 is opened theliquid is admitteddirectly to the orifice 7, which changes the character vof the spraysomeivhat and delivers it far- --ther from the nozzle.

The arrangement of the valve seat in the manner `shown and describedenables the disposition of the valve stem parallel to the pipe, so thatthe stem is reciprocated with little strain or wear on the same or itsbearings and packing in the head. This is of decided advantage asefforts have been made to operate valves with the stems disposed at anangle to the pipe, .which soon Wears the parts so that the liquidescapes and-is thrown into the face of or on to, the per. 'sin of theoperator, which is very disagreea le;

l. My improved sprayer is simple and economical to produce and at thesame time is veryeliieient and durable in use, and is not likely tobecome clogged.

Having thus described my invention, whatv I claim as new and desire tosecureby Letters Patent is:

l. In a sprayer, the combination with the delivery pipe, of achamberedvelbowed nozzle body 'having an internal annular seat at itsouter end, a nozzle tip member with acentral delivery orifice, threadedupon 'said body, a plate arranged in said seat in said body, there beingagasket between said tip and'plate whereby the inner end, the plane ofthe valve seat being at right angles to the longitudinal axis .ofsaidvdeliveiy pipe, a valve coacting with said seat, a valve stemdisposed through the inner end of said body and parallel with' saidpipe, agui de for said siem mounted on said pipe, a valve actuatinglever pivotally mounted on said pipe and pivotally connected to saidstem, and a return spring'tor said i supvalve, said stem guideconstituting a port for said spring.

Q.' In a sprayer, the combination with the delivery pipe, of a chambcredelbowed nozzle body, a nozzle tip member with a central deliveryorilice, a plate supported in Aee a spaced relation `trom said tipmember `to provide a chamber therebetween, said plate having deliveryorifices therein dis osed to deliver at an angle into the chamber etweensaid tip member and plate, and being provided with au inward projectionhaving a.

longitudinal passage therein alined with said delivery orifice ot saidtip. member and provided. with valve seat at its inner end,

said'inward projection being disposed at an angle to the longitudinalaxis of said deliv ery pipe, the plane of the valve seat being atrightangles to the. longitudinal axis "ot' said delivery pipe, a valvecoacting with said seat, and a longitudinally movabley valve stemdisposed through the inner end of Said body and parallel with said pipe.

3. lnI a sprayer, the combination with the delivery pipe, of a chamberedelbow shaped nozzle body, a nozzle tip member having a delivery orifice,a plate disposed in said body, there' being a chamber between said plateand tip member, said plate having a delivery orifice therein arranged todeliver at an angle into the chamber between said tip member and plate,and being provided with an inward projection having a longitudinalpassage therein alined with said delivery oritice of said tip member andwith a valve seat at its inner end, the plane of the valve seat beingsubstantially at right angles to the longitudinal axis of said deliverypipe, a valve eoacting with said seat, a valve stem disposed through'the inner end of said body and substantiallyparallelv with said pipe, aguide Vfor said stem mounted on said pipe, a valve actuating levermountedA on said pipe, and a return spring for said valve, said stemguide constituting a support for said spring.`
